Question

What ordered pair satisfies the inverse of y=3x-2?

a.(1,2)

b.(0,2)

c.(4,2)

d.(4,1)

Answer 1

Isolate x: \[\frac{y+2}{3}=x\] Exchange x into y:\[\frac{x+2}{3}=y\]Test the given points.

Answer 2

So, did you find the answer?

Answer 4

wait :)

Answer 5

is it letter c? @ChillOut

Answer 6

Yes, it is.

Answer 7

kindly explain to me ... why ? @ChillOut

Answer 8

I'll give you the step-by-step:
y = 3x -2.
We add 2 to both sides, then it becomes y+2 = 3x.
Dividing both sides by 3, we get to y+2/3 = x.

Now all that we have to do is switch x by y. Just change their places!
x+2/3 = y. If we test the option 3, we have
(4 + 2)/3 = 2 -> 6/3 = 2, 2=2. See?

Answer 9

I meant test option c
